I found bad caps on the motherboard. Not worth fixing. Replacement ordered.
Thanks for the input everyone.
I hope it's OK to post non-mame related PC issues here. If not, feel free to move to loony bin.
My called me this morning and said that my step-father's PC had shit the bed. I picked it up and brought it home tonight for troubleshooting.
It's an HP desktop PC with an AMD processor from at least 5 years ago, probably longer.
Basically, when you press the power button, the fans all spin up, but it never POSTs. I tried disconnecting the drives, and even removing all the memory, hoping to hear some beep codes or something. I even changed the jumpers on the motherboard to clear the CMOS and pulled the onboard battery. No change.
I even suspected that maybe it was a failing power supply, but swapping in a different ATX power supply makes no difference.
It has onboard video and it never puts out a signal and the monitor goes to sleep.
My next move is to probably disassemble it and blow out all the dust. Maybe even try to boot up the motherboard on the table in case there's a short with the case or something.
I'm kind of stumped. Any ideas?
